“What is the problem we wish to solve when we try to construct a rational economic order? On certain familiar assumptions the answer is simple enough. If we possess all the relevant information, if we can start out from a given system of preferences, and if we command complete knowledge of available means, then problem which remains is purely one of logic.... This, however, is emphatically not the economic problem which society faces.”
Friedrich Hayek, “The Use of Knowledge in Society,” American Economic Review, 35 (January 1945)
